Description

Technical Field

[0001] The invention relates to an adaptive assembly frame vehicle system for cabin section assembly, belonging to the technical field of aircraft section assembly. Background Art

[0002] During the assembly of cabin sections, the cabin is in a vertical or horizontal state. In the vertical state, the rudder is usually pressed, and in the horizontal state, the servo system, instrument cables, inertial group and bracket are usually installed. Therefore, the cabin carrier needs to have the function of vertical and horizontal bearing. The special-shaped cabin has a small space and is difficult to operate. When assembling in the horizontal state, two people are required to work and the operating height needs to be adjusted.

[0003] Based on the estimation of future production and comprehensive analysis of existing sites, it is clear that pulsating production will be used as the production organization model. The key technology of pulsating production is the automatic loading of cabin sections, which is characterized by high transfer frequency. The traditional mode of hoisting loading and unifying the assembly after assembly cannot meet the above requirements. Summary of the invention

[0004] The technical problem solved by the present invention is: to overcome the shortcomings of the prior art and propose an adaptive assembly frame system for cabin section assembly, which is used to realize the rapid acceptance and conversion, vertical and horizontal placement, and lifting and lowering adjustment of cabin sections, and meet the cabin section assembly operation and transportation requirements.

[0018] Furthermore, the upper load-bearing bracket is provided with a plurality of horizontal bearing surfaces, which are installed on the upper surface of the rectangular frame; there is a height difference between the height of each horizontal bearing surface and the height of the vertical bearing surface, so as to avoid interference and collision when the cabin section is put on the shelf.

[0019] Furthermore, the bearing pads are divided into vertical bearing pads and horizontal bearing pads; the vertical bearing pads correspond one-to-one to the vertical bearing surfaces and are all fixed to the edge of the vertical bearing surfaces, and all the vertical bearing pads are coplanar for supporting the cabin sections in a vertical state; the horizontal bearing pads correspond one-to-one to the horizontal bearing surfaces and are all fixed to the horizontal bearing surfaces for supporting the cabin sections in a horizontal state.

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] According to the requirements of cabin assembly operations and transportation such as rapid vertical and horizontal placement, lifting and adjustment, and rapid transfer, combined with the weight and center of gravity before and after cabin assembly, ergonomics and other design inputs, the present invention proposes an adaptive assembly rack system for special-shaped cabin assembly, which includes a pallet and a rack. The pallet meets the cabin load-bearing requirements and is used in conjunction with the rack to meet the design input of rapid vertical and horizontal placement. The rack has strong rigidity and has the functions of being movable and stoppable, liftable, and cabin vertical and horizontal load bearing and positioning.

[0037] 1. Pallet

[0038] The pallet is one of the core components of the present invention. It has a load-bearing function, can support and carry the target cabin, meet the placement requirements of the cabin in a vertical state, provide reliable load-bearing capacity, and ensure the stability of the cabin during the shelving process; it has a positioning function, and the pallet uses a positioning block and a six-leg guide design to ensure the accurate positioning of the cabin during transportation and shelving; it has the execution conditions of "cabin drops and tray moves", and can cooperate with the rack vehicle to complete the rapid load-bearing conversion of the target cabin, making the shelving work efficient and reliable; it has a protective function, and through the anti-slip and shock-absorbing effect of the rubber gasket, it can effectively prevent the cabin from slipping during transportation and assembly, and prevent the cabin surface from being damaged due to contact.

[0039] The pallet material is Q235 steel, and the surface is treated with anti-corrosion to ensure durability and strength for long-term use. Its load capacity is 2T. The pallet is mainly composed of the pallet body, positioning blocks 3, and rubber gaskets 4. Figure 3 shown.

[0040] (1) Pallet body

[0041] The load-bearing capacity of the target cabin can be realized, and the mechanical structure cooperates with the corresponding position of the rack to realize the load transfer of the cabin. The pallet body includes a load-bearing surface 1 and six legs 2. Figure 2 According to the size envelope of the target cabin, the design principle of "the outer size of the load-bearing surface 1 is larger than the target cabin size, and the outer size of the six legs 2 is smaller than the target cabin size" is clarified.

[0042] The load-bearing surface 1 is composed of the main load-bearing surface and the auxiliary load-bearing surface. The main load-bearing surface is realized by a rectangular load-bearing steel plate plus a transverse and longitudinal beam to prevent bending and deformation. According to the envelope of the outer dimensions of the target cabin, the main load-bearing surface is designed as a rectangle of 1000mm×620mm, and the load-bearing steel plate is 40mm thick; the transverse beam runs through the head and tail of the pallet, with a width of 60mm and symmetry along the central axis, and a thickness of 120mm; the longitudinal beam is 440mm away from the tail of the pallet, with a width of 40mm and symmetry along the transverse axis. The auxiliary load-bearing surface is composed of two triangular load-bearing steel plates, both of which are 300mm×370mm in size and symmetrically distributed along the central axis 100mm away from the central axis. The outer side of the triangle hypotenuse prevents possible interference with the racking vehicle, and the inner 200mm×300mm gap is used to avoid the front side load-bearing surface of the load-bearing bracket on the racking vehicle, which is a sufficient condition for realizing "cabin drop tray walk".

[0043] The six legs 2 are symmetrically distributed on both sides of the load-bearing surface, three on each side, with guide blocks at the bottom and a guide angle of 30°, which can be used in conjunction with the counterpart to achieve a correction effect when performing the loading work. According to the design principle that "the outer dimensions of the six legs are smaller than the target cabin dimensions", it is clear that the length of the six legs is 370mm and the width is 60mm. The outer side of the first leg is coplanar with the main load-bearing surface, and the second and third legs are 240mm and 490mm away from the first leg respectively, dispersing the load-bearing capacity and accurately matching the load-bearing result of the racking vehicle.

[0044] After calculation, the center of gravity of the pallet body is located 420mm along the axis starting from the main load-bearing surface. In order to ensure that the center of gravity of the target cabin is collinear with the center of gravity of the pallet in the plumb direction, the positioning block is designed with the center of gravity of the pallet as the coordinate point.

[0045] (2) Positioning block

[0046] The envelope of the pallet and the target cabin is as follows Figure 1 As shown, the positioning block 3 is used to limit the position of the target cabin on the pallet to avoid sliding or offset during transportation and shelving. According to the condition of "taking the main load-bearing surface as the starting point and the target cabin at 420mm along the axis in the vertical direction being collinear", the distributable position of the positioning block 3 is clarified through the model fitting technology. Through anti-overturning design and force analysis, the relevant risks are integrated and the plan of deploying 4 positioning blocks 3 is clarified. The starting point is 190mm symmetrical along the central axis, the length is 100mm, the thickness is 3mm, and there is a threaded hole at the bottom. It is connected to the pallet body by bolts to effectively resist the risk of overturning.

[0047] (3) Rubber gasket

[0048] The rubber gasket 4 is used to isolate the target cabin from the main body of the pallet to prevent the cabin from being damaged due to direct contact with the load-bearing surface; it increases the friction between the cabin and the load-bearing surface to prevent sliding during transportation and assembly. The rubber gasket 4 is a rectangular sheet, laid on the surface of the pallet load-bearing surface 1 and inside the positioning block 3. Its size is 100mm×30mm, with a total of 4 pieces, to ensure that the key positions where the cabin is placed are protected. The rubber gasket material is industrial-grade wear-resistant rubber with high elasticity and pressure resistance. It is fixed with high-strength adhesive, and the rubber gasket 4 is tightly combined with the main body of the pallet, resistant to high temperatures and prevented from falling off.

[0049] 2. Carriage

[0050] The trolley is one of the core components of the present invention, which meets the requirements of high-strength load-bearing, precise docking, flexible movement and vertical and horizontal assembly. The trolley is made of Q235 steel, and the surface is treated with anti-corrosion to ensure durability and long-term strength. The trolley adopts a frame structure, which mainly consists of a load-bearing mechanism 5, a load-bearing pad 6, a lifting mechanism 7, and a motion mechanism 8. Figure 4Among them, the load-bearing mechanism 5 ensures the precise matching of the pallet and the trolley, which is the key to realize the "cabin drop and tray move".

[0051] (1) Load-bearing structure

[0052] The load-bearing mechanism 5 provides comprehensive support to the tray and the target cabin through the upper / lower load-bearing brackets and the left / right load-bearing brackets. Figure 5 As shown in (a) to (d) in the figure. The upper load-bearing bracket is strongly coupled with the notch of the tray and the six legs. In order to achieve "cabin falls and tray moves", it is clear that the position and size of the upper load-bearing bracket's upper load-bearing surface should be within the envelope of the target cabin, and the strength should ensure that the load-bearing transfer process is safe and accurate, and the operation is safe.

[0053] 1) Upper bearing support

[0054] Taking the center of gravity of the pallet as input, in order to ensure that the center of gravity of the target cabin, the center of gravity of the pallet and the center of the trolley are in the same line along the vertical direction, the design direction of the upper / lower load-bearing bracket using a frame structure is clarified. And through model fitting and force analysis calculation, it is clarified that the center of gravity of the upper / lower load-bearing bracket is located at 1520mm from the front end surface along the axisymmetric center line to the handle direction, such as Figure 6 shown.

[0055] Considering the weight of the target cabin before and after assembly and the characteristics of Q235 steel, it is determined that the thickness of the upper support is 90mm and the width is 100mm. Through further force analysis, it is determined that the upper support has 5 vertical bearing surfaces.

[0056] Taking into account the design requirements of the pallet "the outer dimension of the load-bearing surface is larger than the target cabin size, and the outer dimensions of the six legs are smaller than the target cabin size", the truck "the position dimension of the load-bearing surface on the upper load-bearing bracket should be within the envelope of the target cabin", and the design ideas of the coordination between the upper load-bearing bracket and the pallet, the six legs of the pallet can simultaneously pass through the five vertical load-bearing surfaces of the upper load-bearing bracket in the vertical direction.

[0057] The structure of the interface between the vehicle body and the pallet is designed according to the outline size of the target cabin. The pallet and the 5 vertical bearing surfaces of the upper bearing bracket are matched in mechanical design. The outer envelope size of the target cabin product is between the pallet main body bearing surface 1 and the six legs 2. Therefore, when the pallet carrying the target cabin falls from top to bottom on the upper bearing bracket of the basic bearing mechanism of the rack, the bearing transfer phenomenon between the pallet and the rack gradually appears. When the pallet moves below the upper bearing bracket of the rack, the bearing transfer is completed. The target cabin is located on the upper bearing bracket of the rack, realizing "cabin falls and tray moves". Figure 7 As shown, ensure the stability and safety of the cabin on the pallet and the trolley.

[0058] The front vertical bearing surface is rectangular, with a size of 290mm×150mm, connected to the base support, and symmetrical along the horizontal axis; the left front / left rear vertical bearing surface of the vehicle is symmetrical with the right front / right rear vertical bearing surface of the vehicle along the horizontal axis, the left front / right front vertical bearing surface of the vehicle is 530mm away from the horizontal axis, the left rear / right rear vertical bearing surface of the vehicle is 610mm away from the horizontal axis, and the left front / left rear vertical bearing surface of the vehicle is 500mm and 810mm away from the front outer surface of the vehicle respectively. The vertical bearing surface and the tray adopt a coupling design to ensure safe and efficient load transfer of the cabin.

[0059] Through force analysis and the principle of interference avoidance, four horizontal bearing surfaces are set on the upper load-bearing bracket. The left front / right front horizontal bearing surface is symmetrical along the horizontal axis of 370mm, with a length of 213mm, and the length is consistent with the basic bracket of the vehicle body, both 100mm; the left rear / right rear horizontal bearing surface is symmetrical along the horizontal axis of 370mm, with a length of 213mm, and the length is consistent with the basic bracket of the vehicle body, both 100mm. In terms of height, the four horizontal bearing surfaces are set to 150mm to avoid the vertical bearing surface, which can effectively avoid interference and collision.

[0060] 2) Lower bearing support

[0061] The lower load-bearing bracket structure is also a frame type, which is integrally welded with the left / right load-bearing bracket to form a high-rigidity frame to provide basic bearing support; the positioning rod is used to prevent the lower load-bearing bracket and the upper load-bearing bracket from moving radially, and the lifting mechanism of the lifting mechanism controls the overall movement of the upper load-bearing bracket in the vertical direction. The frame is 90mm thick and 100mm wide, and multi-point support is set at the part connected to the lifting mechanism to prevent deformation caused by load transfer.

[0062] 3) Left and right load-bearing brackets

[0063] The left and right load-bearing brackets are the main load-bearing components, equipped with legs and load-bearing rods. A single load-bearing bracket has two legs, deployed on both sides of the bracket, with a size of 80mm×80mm×400mm. A single load-bearing bracket has two load-bearing rods, arranged up and down, with a size of 60mm×60mm×835mm. The load-bearing rods and legs are welded to ensure load safety.

[0064] (2) Loading pad

[0065] The bearing pad 6 is divided into a vertical bearing pad and a horizontal bearing pad, which are respectively fixed to the vertical bearing surface and the horizontal bearing surface of the upper load-bearing bracket. The two bearing pads are respectively used for bearing the target cabin in the vertical state and the horizontal state.

[0066] The vertical bearing pads are fixed to the edge of the vertical bearing surface by screw connection. The vertical bearing pads have a size of 150mm×100mm×18mm. The 5 vertical bearing pads are coplanar to ensure that the cabin is placed stably in the vertical state. The vertical bearing pads are made of polyurethane to prevent the cabin from sliding.

[0067] The horizontal bearing pad is fixed to the horizontal bearing surface by screw connection. The size of the horizontal bearing pad is 80mm×215mm×42mm. The four vertical bearing pads are coplanar to ensure that the cabin is placed stably in the horizontal state and the placement process does not interfere with the vertical bearing pads, which is easy to operate and adjust. The horizontal bearing pad material is polyoxymethylene to prevent possible bumps and damage to the cabin.

[0068] (3) Lifting mechanism

[0069] The lifting mechanism 7 includes six components: an oil tank, a pedal mechanism, a hydraulic oil cylinder, a lifting mechanism, an oil pipe, and a pressure relief valve, which can realize the lifting and lowering of the frame vehicle. The pedal mechanism is deployed at the front side of the lower load-bearing mechanism of the frame vehicle. As the main power element, the hydraulic oil in the oil tank is pressed into the oil pipe by stepping on the foot, and finally reaches the oil cylinder; the oil cylinder is deployed at the four corners between the load-bearing mechanisms of the frame vehicle and is connected to the lifting mechanism. The oil cylinder continuously extends the piston rod due to the pressure. The latter is mechanically connected to the lifting mechanism, so the lifting mechanism is extended. Because the lifting mechanism is rigidly connected to the upper load-bearing surface of the frame vehicle, the lifting of the frame vehicle is realized; the pressure relief valve is turned to release the pressure of the piston rod of the oil cylinder, and the upper load-bearing surface of the frame vehicle descends under the action of gravity, compressing the lifting mechanism, and the hydraulic oil flows back to the oil tank through the oil pipe, and the frame vehicle completes the descending action.

[0070] The lifting mechanism 7 can complete the adjustment of the carriage within a range of 300mm, and realize the height adjustment of the carriage from 750mm to 1050mm, ensuring the assembly operation of the cabin sections at different heights.

[0071] (4) Movement mechanism

[0072] The motion mechanism 8 adopts the design of floor brake and caster to control the movement and stop of the trolley. There are 4 casters in total, and the material is selected to be wear-resistant and pressure-resistant large-diameter silent lock wheels. While supporting the weight of the trolley and the product, it can roll smoothly on the ground and take into account the steering function, so that the trolley can move flexibly in the assembly area. There are 4 floor brakes in total, installed next to the casters, used to stop and fix the trolley, ensure the stability and safety of the trolley during operation, and prevent sliding and accidental movement.

[0073] The working principle of the system designed in the present invention is as follows: placing the cabin products on the pallet, using a carrier such as AGV to lift the pallet, transporting it to the top of the racking vehicle, slowly dropping it, and vertically dropping the cabin onto the vertical bearing pad 6 of the racking vehicle, and the pallet moves away from the production area together with the carrier, realizing "cabin drops and tray moves away", greatly improving the efficiency and safety of cabin shelving; when vertical or horizontal conversion is required, the racking vehicle can provide the placement conditions for the vertical or horizontal conversion of the target cabin, realizing "rapid vertical or horizontal placement" to ensure product safety; the operator can use the lifting mechanism 7 to adjust the relative position of the cabin and the operator in the vertical direction according to the assembly needs, so as to perform precise assembly operations at different heights; when the product needs to move or stop, the operator can use the casters to operate the vehicle to move or use the ground brake to stabilize the vehicle position when necessary to ensure safety.

[0074] After multiple application tests, the present invention has been proven to have significant effects in cabin assembly work. It can be used with a carrier to achieve rapid vertical-horizontal conversion of cabins, ensure the stability and safety of the vertical-horizontal conversion, improve work efficiency, and shorten the time by 10 times compared to traditional conversion operations. In summary, the present invention greatly improves the operating efficiency and transportation efficiency of special-shaped cabin assembly, improves safety, saves a lot of time and cost for enterprises, and also ensures the safety of products.

[0075] The above-described embodiments are only preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
